The variable i0 was the polarization current and ei0 its estimation error. The variable γ was the exponential decay ratio and eγ its estimation error. The maximum distance, root means square error, sum of squares of errors, standard error of the estimate, adjusted goodness-of-fit coefficient of multiple determination, predicted residual error sum of squares and multiple predicted residual sum error of squares were identified by parameters Dmax, RMSE, SSE, SE, \(r_{a}^{2}\), PRESS and MPRESS (for m = 3), respectively. Legends of TG1-F, TG2-F, TG3-F, TG4-F, TG5-F and TG6-F were defined in Experiment subsection
